Abstract

L'invention concerne un procédé, des systèmes et un appareil d'ordonnancement adaptatif destinés au service de données en continu soit pour un canal à porteuse unique, soit pour un canal à porteuses multiples. Cet ordonnanceur adaptatif attribue la transmission de données à l'aide permutations circulaires mixtes et de sélections d'utilisateur de CIR maximum, en fonction d'une valeur seuil prédéterminée relative à la vitesse de transmission de données en continu cible. Cet ordonnanceur permet d'obtenir une grande flexibilité pour un service de données en continu, et exploite une diversité d'utilisateurs multiples dans un système à porteuse unique et une diversité de fréquence supplémentaire dans un système à porteuses multiples.
